We still need to set the hooks to prevent improper manipulations thereafter
at the loader prompt, but as it is we're actively preventing loaddev from
being set correctly in some circumstances (ZFS in particular) and doing more
work than needed with currdev -- that hook in particular validates it as a
correct device, which we can assume isn't needed in this context.

Support for NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, NO_MAN, NO_PROFILE,
and NO_WARNS as deprecated in 2014 with a warning added for each one
found. Turn these into error in preperation for removal of compatability
support before FreeBSD 13.
This was previously committed in r354909 and reverted in r355011 due to
unforseen impacts on ports. I've since corrected all amd64 and i386
ports reported in prior runs as well as instance of these variables I
found via grep.
As with the rest of pjdfstest, tag the symlink with package=tests.
The tests -> . symlink seems a little strange but that's independent
of pkgbase.

For historical reasons the "remote magtape protocol module" rmt gets
invoked as /etc/rmt, which is a symlink to /usr/sbin/rmt. Put it in the
utilities package, as /usr/sbin/rmt is.

fdatasync is essentially a subset of fsync (and may be exactly fsync,
depending on filesystem and development effort) and operates only on
a provided fd.

If we hit an error at this level, we are almost certainly not in any kind
of sane state where autoboot can do the right thing. Instead of letting it
try and probably failing, disable autoboot so they immediately get kicked
into a loader prompt for manual remediation/diagnosis.

This is taken from the arm64 version, with the following simplifications:
- Our current pmap implementation uses a 3-level paging scheme
- The "mode" field has been omitted since RISC-V PTEs don't encode
typical mode attributes

In particular on amd64 this eliminates an atomic op in the common case,
trading it for IPIs in the uncommon case of catching CPUs executing the
code while the filesystem is getting suspended or unmounted.
This is a wrapper around smp_rendezvous_cpus which enables use of IPI
handlers which can fail and require retrying.
wait_func argument is added to to provide a routine which can be used to
poll CPU of interest for when the IPI can be retried.
Handlers which succeed must call smp_rendezvous_cpus_done to denote that
fact.

When the receive ring cannot be filled with mbufs, due to lack of memory,
no more interrupts may be generated to fill the receive ring later on.
Make sure to have a watchdog, to try refilling the receive ring from time
to time, hopefully when more mbufs are available.

It was saved from the initial purge of drivers in fcp-101 due to being
the onboard Ethernet device on a number of sparc64 machines. Now that
sparc64 is gone, it serves little purpose (PCI cards exist, but are rare
and are unlikely to have been deployed outside Sun systems).
